Your BMW head has an identifying casting number that will be needed in order to ensure that you get the correct cylinder head. This auction is for the 8400 casting only. This number is cast into the head in the form of raised numbers. Please include this information along with your vehicle's year with any correspondence such as a Paypal payment.

We will accept your old cylinder head no matter what is wrong with it as long as it includes all the parts that our head came with. You will never be charged extra because your old head is damaged. Cracked head? OK! Bent valves? OK! Head taken apart? OK! (as long as you put all of the parts in the box). We have no up-front core charge. Our comprehensive inventory includes heads for domestic or import models and a 12-month unlimited mileage guarantee.
